Definitions
- the invention is in the field of polymer formation. More particularly, the invention is in the field of polysuccinimide and polyaspartic acid formation. Background
- Polyaspartic acid has been formed by a number of methods.
- polysuccinimide can be produced with unexpectedly high yields using maleic anhydride and ammonia at elevated temperatures.
- the resulting polysuccinimide can be base hydrolyzed to produce polyaspartic acid.
- a low molecular weight polysuccinimide having a molecular weight within the range of 1000-2000 Mw can be produced in yields exceeding 60%.
- the maleic anhydride forms an adduct with ammonia.
- Adding previously formed polysuccinimide prior to elevating the temperature above 200°C results in a relatively high molecular polysuccinimide having a weight average • molecular weight of greater than 3000.
- a weight average molecular weight greater than 12,000 is achievable.
- the molecular weight will exceed 3000 Mw.
- the molecular weight will be within the range of from 3200 to 12,000.
- the molecular weight will be within the range of from 3200 to 10,000.
- the preferred polymerization temperature range is from 200°C to 260°C.
- a more preferred polymerization temperature range is from 220°C to 260°C.
- the most preferred polymerization temperature range is from 220°C to 240°C.
- the yield can be increased by increasing the length of the reaction.
- 6 to 14 hours is preferred. More preferred is 7 to 10 hours.
- Increasing the amount of ammonia relative to the amount of maleic anhydride can also increase yield.
- 1 to 12 times the number of moles of maleic anhydride is preferred, two to five times is more preferred, and two to three times is most preferred.
- maleic anhydride eguivalents such as maleic acid and its salts are useable.
- polyaspartic acid includes the salts of polyaspartic acid.
- the product was transferred to a reaction vessel and heated to a 135°C oil bath temperature for a reaction mixture temperature 115°C. During the four hours of heating, water formation indicative of a condensation reaction was observed. Upon completion of the reaction , a brittle solidified product was observed. After hydrolysis, GPC clearly showed the presence of a small amount of polymer. Titration showed about 20% polymer.
- Example 2 The product of Example 2 was ground; 15 grams were placed in a test tube and heated for 4-5 hours at a 150°C oil bath temperature (140°C reaction mixture temperature). After hydrolysis, GPC data showed the presence of a polymer shoulder. Titration showed 30% polymer.
- Example 2 The product of Example 2 was ground; 15 grams were placed in a test tube and heated for 5 hours at 180°C oil bath temperature (170°C reaction mixture temperature). After hydrolysis, GPC data clearly showed about 50% polymer. Titration data confirmed this amount.
- Example 5 The product of Example 2 was ground; 20 grams were placed in a test tube and heated in an oil bath for 5 hours at 220°C. - __> -
- the product was water insoluble. GPC analysis of the hydrolyzed product evidenced a strong polyaspartic acid peak. Titration showed 90% polysuccinimide.
- reaction mixture temperature 110°C reaction mixture temperature 110°C.
- water formation indicative of a condensation reaction was observed.
- a brittle solidified product was observed.
- GPC showed the presence of no polymer. Titration data showed less than 5% polysuccinimide formation.
- the product was transferred to a reaction vessel and heated in an oil bath temperature to a reaction mixture temperature 120°C with a corresponding oil bath temperature of 135°C. During the fourteen hours of heating, water formation indicative of a condensation reaction was observed. Upon completion of the reaction , a yellowish hard material was observed. Titration showed 0% polymer. GPC results were consistent with the titration. - -
- polysuccinimide was formed in significantly greater yields at temperatures above 150° C. At temperatures of 150°C or lower a maleic anhydride/ammonia adduct was formed. It appears that at elevated temperatures that adduct participated in a polymerization reaction. Once the 200° C • threshold was reached or surpassed GPC and titration studies gave clear evidence of polysuccinimide formation, and under these elevated temperatures the yield was high, over 70%. At temperatures above 220°C the yield attained the maximum of 100% of theoretical and generally exceeded 90% of theoretical. At temperatures above 150°C, a yield of 60% theoretical was obtained. At temperatures exceeding 170°C, at least 70% of the theoretical yield was obtained.
- Example 9 The product of Example 2 is placed in a test tube and mixed with half its weight of previously formed polysuccinimide which has a weight average molecular weight of 3000. The reaction mixture is heated to 220°C for a period of 10 hours. A polysuccinimide having a molecular weight of 10,000 is produced. The polysuccinimide product is base hydrolyzed using ammonium hydroxide to produce polyaspartic acid.
- Example 10 The product of Example 2 was placed in a test tube and mixed with a previously formed low molecular weight polysuccinimide, having a weight average molecular weight of 1000. The reaction mixture was heated to 220°C for a period of 10 hours. A polysuccinimide having a molecular weight of 6000 was produced. The polysuccinimide product was base hydrolyzed using ammonium hydroxide to produce polyaspartic acid.
- Example 11 The product of Example 9 is placed in a test tube, mixed with and reacted with the product of Example 10. The reaction mixture is heated to 220°C for 12 hours. A polysuccinimide have a molecular weight of 12,000 is produced. The product is base hydrolyzed to form a polyaspartic acid.
- Examples 9 through 11 show that molecular weight of the polymer can be increased by using previously formed polysuccinimide and adding it to the reaction mixture.
